To all whom t may concern: 4

Be it known that I, STEPHEN IVAN FEKETE, a citizen of the United States, residing at Detroit, countyof Wayne, State of Michithe purpose of controlling the flow of air through the radiator. v

As is well known to those skilled in the art, economy of operation of the ordinary water cooled internal' combustion engines employed in automobiles depends largely on the maintenance about the engine of a temperature which is as close to the boiling point of water as possible. This is particularly true at the present time when the fuel employed includes a large proportion of low grade distillates which are not easily vaporizable at ordinary temperatures. Accordingly, it is desirable to provide a shutter for regulating the How of air through the radiator. By this means the flow ofl air through the radiator may be entirelyv shut od' when the engine is first started, thereby causing the temperature in the cooling sysI tem to rise rapidly until the point of 'maximum eiciency is reached. After this, Ythe shutter may be opened to give whatever flow of air through the radiator is requisite to maintain the temperature of maximum efficiency under the conditions of operation which are then prevailing.

My invention provides a radiator shutter which is applicable to the ordinary radiator and which when so applied is attractive in appearance but does not change noticeably the lines of the car. Itis so constructed that it does not become noisy or rattle, even after a long period of use. llt provides means for regulating the flow of air through the radiator quickly and accurately and atthe will of the operator. Y

titl

lin the drawings,li`igure 1 is a vertical section showing my radiator shutter and casing therefor applied to the radiator of an ordinary automobile, thepradiator being shown in dotted lines.

lEig. -2 is a front elevation ofthe radiator shutter and casing.

Fig. 3 is a portion of a side section similar to Fig. l showing the position of the slats when the shutter is wide'open.

Figz is an enlarged horizontal section on line 4 4: of Fig. 1 and shows the method of constructing thebearings for'thc trnnnions of the slats.

Referring to the drawings, at A is shown the radiator, and at B the filler. These parts form no part of my invention and therefore have been indicated indotted lines in the drawings. rThe radiator shutter is comprised of a series of slats 11 secured to trunnion rods 12, which are carried in a frame 13 of U-section. This frame 13 is carried in the radiator shutter casing 6, which is of the general form of the radiator with which it is to be used as seen in Fig. 2. The radiator shutter casing 6 has a fiange 14 extending rearwardly substantially parallel with the corresponding portion of the radi,

' Each slat 11 is provided with a half-round grooved portion 15 located near its lower edge so that when the radiator shutter is closed, the half-round grooved portion 15 will lie about the portion of the slat which is mounted on the trunnion of the slat next below and the shutter will present a substantially smooth or flat appearance on thel shown in Fig. 1, is built up of members 13 exterior. The frame which carries the slats,A

which are vU-shaped in cross sectionV (see f Fig. 4:) said members beingfilled with a,

strip or bar of some'dense non-metallic material 17, as for instance that which is ordinarily known in commerce as brake-lining and which contains asbestos for one of its components. Each trunnion rod is provided with a collar 18 which rests adjacent the side of the strip of brake-lining material 17 and receives the end thrust` of the slat. The trunnion 12 extends through the brake lining but the hole 19 in the U-shaped supporting member 13 is larger than the diameter of the trunnion rod so that there is no possibility of the trunnion rod coming in means. I have'found asa result o even after vbeing run for some thousands of v miles under trying conditions shows no 4signs of becoming nolsy or wearing unduly.

The operating means will now be described. Each of the slats is provided with a rearwardly extending lug 20 pivoted at j21 to a bar 22. This bar 22 is similar in shape to the- U-shaped member 13 and also contains a strip 17 of the brake lining material so that there is no contact between the lugs and pivots and the bar 22.

The bar 22 is provided with a lug 24 through which extends a bar 25 pivoted at its upper end to a bell crank 26 which is itself pivoted at 7 to the rearwardly extending flange 14. The bell crank lever 26 is moved by a rod 28 which extends back to the dash board of the vehicle, not shown, or to some other point within the reach of the operator of the vehicle. The rod 25 is provided with a collar 27 which rests against the upper side of the lug 24, and at 28 with a nut there being a spring 29 between the nut and the lug 24. Spring 29 is employedv to take care of the backlash between the connecting parts of the operating mechanism.

What I claim is:

1. The limproved radiator shutter comprising a casing adapted to be detachably secured to the radiator of an automobile, pivoted slats within the said casing, each of said slats being provided with trunnions, strips of brake lining material secured, to opposite sides of the -interior 0I said casing having holes therein to receive the said trunnions, and operating means for moving said slats 1n unison. y

2. The improved -radiator shutter com- Lacanau.

prising a casing adapted to be detachably securedr to the radiator' of an automobile, pivoted slats within the said casing, each of said slats being provided with trunnions, strips of brake 1min material secured to opposite sides of the interior of said casing having holes therein to receive the said trunnions, each of said slats being provided with a rearwardly extending lug, a bar pivotally connected to each of said lugs and means within the reach of the operator for moving said bar.

3.' The improved radiator shutter comprising a casing adapted to be detachably secured tothe radiatorv of an automobile, pivoted slats within the said casing, each of said slats being provided with trunnions, strips of brake linin material secured to opposite sides of the ulterior of said casing having holes therein to receive the said trunnions, each of said slats being provided with a rearwardly extending lug, a bar pivotally connected to each of said lugs and means within the reach of the operator for moving said bar, a bar operating the slats in unison, and a strip of brake llning material interposed between the lugs and the bar to prevent rattling.

4. rlhe improved'shutter comprising a casing adapted to be secured to the radiator of an automobile, a series of slats and a series of trunnion rods one for each end of each slat, each of said slats having an ofiset portion alon one edge extending inwardly toward tie radiator and forming a groove, and an oH-set curved portion along the other edge which extends inwardly toward the radiator and is adapted to tit within the groove of the adjacent slat, one of said trunnions being mounted in each offset curved portion at each end thereof upon which said slats are pivoted, said portions being arranged so that when the slats are closed" they present an exterior surface which is substantially fiat.

.In testimony whereof I aiix my signature in presence of two witnesses.
